Traxxas Spur Gear 46-tooth Steel Wide-Face 1.0 Metric Pitch TRX6447R

Overview

The Traxxas Spur 46-tooth, Steel (wide-face, 1.0 metric pitch) TRX6447R is a precision-engineered transmission component designed for RC enthusiasts in the UK who demand maximum performance and durability from their Traxxas models. This machined-steel spur gear is engineered to withstand extreme bashing, competitive speed runs, and demanding off-road conditions. Whether you're piloting a brushless short-course truck, sand car, monster truck, or rock crawler, this spur gear represents a critical upgrade for fine-tuning your RC vehicle's performance characteristics.

Traxxas spur gears are renowned among RC hobbyists for their ability to balance acceleration and top speed depending on your running conditions and driving style. By changing gear ratios, you can optimise your vehicle's transmission to suit different terrains, weather conditions, and performance objectives. The 46-tooth configuration is a popular choice across Traxxas's extensive range of vehicles, making it an essential spare part for serious RC car UK enthusiasts. This replacement gear is manufactured to exacting Traxxas standards and comes from an authorised UK retailer with genuine products and expert support.

Perfect for weekend bashers, competitive racers, and everyone in between, the Traxxas Spur 46-tooth delivers the reliability and performance you expect from Traxxas engineering. If you own any of the compatible Traxxas models listed below—including the Maxx Slash, Funco Motorsports, WideMaxx Monster Truck, X-Monster, or XRT series—this spur gear is an investment in consistent, predictable performance.

Key Features

• Machined from Solid Steel — This spur gear is precision-engineered from high-quality solid steel, which provides superior strength and longevity compared to plastic alternatives, ensuring it can handle the extreme forces generated by high-powered brushless RC vehicles without stripping or breaking.
• Extra-Wide Steel Teeth — The wide-face design of the teeth increases the contact surface area with the pinion gear, distributing power more evenly and reducing stress concentration, which translates to ultimate power handling and extended component lifespan even during aggressive bashing and speed runs.
• 1.0 Metric Pitch Specification — This industry-standard pitch measurement ensures perfect compatibility with your Traxxas transmission and pinion gears, eliminating fitment issues and ensuring smooth, efficient power delivery to your RC vehicle's wheels.
• 46-Tooth Configuration — The 46-tooth count is precisely engineered to deliver a balanced gear ratio that serves as a versatile starting point for most Traxxas models, allowing you to either dial in more aggressive acceleration by switching to a higher tooth count, or increase top speed with a lower tooth count depending on your track or terrain conditions.
• Performance Tuning Tool — By changing spur gear ratios, you can fine-tune your RC vehicle's acceleration, top speed, and overall performance characteristics to match specific running conditions, whether you're navigating technical rock-crawling courses, high-speed oval tracks, or mixed terrain bashings.
• Authorised Traxxas Component — This is a genuine Traxxas replacement part, not an aftermarket copy, ensuring perfect fit, finish, and reliability with your brushless RC truck, monster truck, sand car, or crawler.

Technical Performance

The Traxxas Spur 46-tooth represents premium engineering in RC transmission components. Manufactured from solid, machined steel with a 1.0 metric pitch specification, this spur gear is designed to withstand the extreme torque and power output of modern brushless RC vehicles, including high-performance models like the 8S-capable Funco Motorsports sand car and the 6S-equipped Maxx Slash short-course trucks. The wide-face tooth design is the key to this gear's durability and performance—the expanded contact surface distributes the enormous forces generated by brushless motors across a larger area, reducing the peak stress on individual teeth and preventing the premature stripping that can occur with narrower, plastic alternatives. This engineering approach makes the gear equally suitable for gentle technical crawling, where precise throttle control minimises shock loads, and for extreme high-speed bashing where sustained power delivery demands maximum durability. The machined-steel construction also provides better dimensional accuracy than cast alternatives, ensuring consistent meshing with your pinion gear and smoother power transmission. For UK RC enthusiasts running competitive or recreational brushless RC setups, this gear serves as a critical wear item that should be inspected regularly and replaced when teeth show signs of wear. Whether you're pushing your vehicle to its performance limits or simply maintaining your pride and joy, the Traxxas Spur 46-tooth delivers the quality and reliability that Traxxas is recognised for worldwide.

Frequently Asked Questions

• Which Traxxas models is the 46-tooth spur gear compatible with? — The Traxxas Spur 46-tooth TRX6447R is compatible with an extensive range of Traxxas vehicles including the Maxx Slash 1/8 4WD 6S Brushless Short Course Truck (all colour variants), the Funco Motorsports Pro Scale 8S 2WD Electric Sand Car, the WideMaxx Monster Truck, the X-Monster chassis, the XRT VXL-8S, and the XRT Ultimate. Always consult your owner's manual to confirm the correct gearing for your specific model and running conditions.
• What is the difference between a 46-tooth and other spur gear options? — Traxxas manufactures spur gears in multiple tooth configurations to allow performance tuning. A 46-tooth gear represents a mid-range option—choosing a higher tooth count (such as 50 or 54 teeth) will increase acceleration and reduce top speed, whilst selecting a lower tooth count (such as 42 teeth) will enhance top speed at the cost of acceleration. Your vehicle's manual will specify recommended gearing options for different driving styles and track conditions.
• Why are the teeth described as extra-wide and wide-face? — The wide-face design increases the tooth contact area with your pinion gear, which distributes power more evenly and reduces stress concentration on individual teeth. This wider surface contact is particularly important for brushless RC vehicles, which can generate enormous torque, making wide-face gears more durable and less prone to stripping than narrower alternatives.
• Is this a genuine Traxxas part or a cheap aftermarket copy? — This is a genuine authorised Traxxas component manufactured to Traxxas specifications and quality standards. Purchasing authentic parts from an authorised UK retailer ensures perfect compatibility, consistent performance, and warranty coverage, avoiding the reliability problems and poor fitment that can result from counterfeit alternatives.
• How often do I need to replace my spur gear? — Spur gear lifespan depends on how heavily you use your RC vehicle, the surfaces you drive on, maintenance practices, and your driving style. Regular inspection of teeth for wear, chips, or stripping is recommended. When you notice visible damage or teeth beginning to wear, replacement is prudent to maintain smooth power transmission and prevent secondary damage to your pinion gear or transmission.
• What tools do I need to install this spur gear? — You will need to refer to your Traxxas vehicle's owner's manual for specific installation instructions and tool requirements. Generally, spur gear installation involves removing the transmission cover, taking out the old gear, and carefully installing the new gear, ensuring proper alignment with the pinion. A socket set and hex driver set are typically required.
